ROTARY MAGAZINE FOR LOOMS.

Specification of Letters Patent. Patented pgq 16, 1919 Application filedMay 27, 1919. Serial No. 300,087.

To all whom it may concern:

Be it known that I, ALONZO E. RHOADES, a citizen of the United States,residing at I-lopedale, county of Worcester, and State of Massachusetts,have invented an Improvement in Rotary hlagazines for Looms, of whichthe following description, in connection with the accompanying drawings,is a specification, like characters on the draw ings representing likeparts.

The present invention relates to improvements in the rotary magazines ofweft replenishing looms, such magazines being adapted to hold a largenumber of weft carriers or bobbins which are to be transferred one byone into the working shuttle; and the improvements more directly relateto the means for maintaining the bobbin engaging ends of the heads ofthe magazine in alincment parallel with the axis of the shut tle towhich the weft carriers or bobbins are to be transferred. Heretofore,the heads of the rotary magazine were mounted upon a support forrotative movement to carry the filling carriers or bobbins one by one tothe transfer position. at which time, the longitudinal axis of thebobbin which is to be transferred to the shuttle must be parallel to thelongitudinal axis of the shuttle, otherwise damage is liable to resulteither to the shuttle or carrier or other parts of the loom. Such rotarymagazines are usually designed to have the heads thereof adjustablerelatively toward or away from each other to adapt the magazines tobobbins or filling carriers of different lengths. but when the headshave been thus adjusted. the alinement of the bobbin end engaging meanson the two heads -are liable to he accidentally moved out of theiralined position, with the result that when a. filling carrier or bobbinpositioned for transfer itsaxis would not coincide with or be parallelto the longitudinal axis of the shuttle. and damage would result asabove indicated.

In accordance with the present invention, the rotary magazine has theheads adjustable toward and from each other as required. and means areprovided to prevent relative rotative movement of the heads of themagazine during the time the heads are adjusted toward and from eachother, the result being that the bobbin end engaging means carried bythe two heads remain in their original a-linenient parallel to thelongitudinal axis of the shuttle into which the filling carriers are tobe transferred.

In accordance with another feature of the present invention, the partsof the magazine are so formed and related and connected to the rotary,thread guide that when the rotar thread guide is removed from themagazine, one of thebobbin holding heads of the magazine may be removedwith it Without disturbing the relative rotative position of the headand the rotary thread guide with which it is associated.

Other features of the invention in addition to the above willhereinafterbe described in connection with the accompanying drawingswhich illustrate one good practi cal form of the invention, and then thenovel characteristics and combinations Will be described by the claims.

In the drawings p v Figure 1 is a vertical longitudinal section of arotarymagazine for filling replenishing looms containing the presentinvention;

Fig. 2 is a transverse section on the line 22 of Fig. 1. H

In its general features they rotary magazine and its cooperatingrelation with other features of filling replenishing looms may begenerally similar to the well known Draper or Northrup loom, asillustrated, for example. by Letters Patent of the United States. X0.529.940, November 27, 189- and upon such general features of the rotarymagazine the present invention improves.

As indicated in the accompanying drawings. 1 is a stand or bracket fixedto a stationary part of the loom, and in the present instance it isformed as a disk-like member in which isvmounted the supporting stud' 2.The supporting stud 2 isprovided with a shoulder 23 which bears againstthe hub-like portion 4 of the stand. and the outer end portion 5 of thesupporting stud is provided with screw-threads on which is placed theclamping nut 6 whereby the supporting stud is .held in fixed positionrelative to the stand 1.

The supporting stud 2 may be variously contrived, butas indicated in thepresent instance, it has the barrel-like portion 7 and the extended endportion 8 on which is mounted for rotation the elongated sleeve 9,against the end 10 of which a washer 11 rests under the'clamping actionof the nut 12 threaded to the end of the stud 2, the construetion beingsuch that the sleeve 9 may be rotatively supported upon the support-'ing stud, a shoulder 18 afi'ording one good suitable mea or preventingrelative longi tudinal movement of the sleeve on the stud.

The sleeve 9 is provided with a large interior chamber 11 surroundingthe large cylindrical part 7 01 the stud and affording an oil receptaclefor the transmission of lubricant between the sleeve and stud. The stud:2 is provided with a longitudinally ex tending duct 15 and a radialportion 16 communicating with the large interior chamber 14. Exterior tothe duct 15 is an oil receiver 17 having communication with the duct 15for the transmission of oil to the large chamber 1% of the sleeve.

One of the heads of the magazine is rigidly connected with the sleeve 9.In the resent instance of the invention, the head 18 which is providedwith sockets 19 or other means for engaging the butt ends of the bobbinsis rigid with the sleeve 9, preterably by being formed integraltherewith, it being obvious, of course, that the rigid connectionbetween the sleeve and head may be otherwise contrived. The head 18 maybe provided with the usual ratchet teeth or other means 20 for givingrotary movement of the head and sleeve as the filling carriers orbobbins are moved to transferring pos1- tion.

The elongated sleeve 9 has an end portion 21 of reduced diameter forminga shoulder 22 against which bears one end of the elongated hub 23carrying the rotary thread guide 24. The rotary thread guide and its hubare suitably connected to the sleeve 9 to rotate therewith byappropriate means, which in the present instance of the invention,consists of a clamping screw 25 passing through the hub and engaging asubstantially fiat surface 26 on the sleeve, the construction being suchthat when the parts are assembled as indicated, the bobbin end engagingmeans on the two heads of the magazine will be held in alincment withthe axes of the bobbins parallel with the longitudinal axis of theshuttle.

The other head of the magazine indicated at 27 is provided with a seriesof bobbin end engaging means for engaging the tip ends of the bobbins.In the present instance these are shown as the yielding fingers 28 whichmay be of usual construction. The magazine head 27 is mounted on theextended hub portion 23 of the rotary thread guide, and the hub 29 ofthe magazine head 27 is provided with a key-way 30. T he extended hub'23 is similarly provided with a key-way 31, and a kev 32 engages thekeyways of the hub and the head to prevent relative rotative movementbetween the two, and permit longitudinal adjustment of the head '37 onthe elongated hub 23 oi the rotary thread guide.

When the magazine head 27 has been adjusted toward and from the opposinghead 18 in accordance with the requirements of the bobbins being' used,it may be clamped or held in such adjusted position by suitable means.such. "for instance, as tl clamping screw 33 which passes through thehub Q" of the head 27 and engages the elongated hub 2?) of the rotarythread guide. The construction is such that when the rotary thread guide2+ and its hub 22- have been adjusted and secured in position upon thesleeve 9, the bobbin end engaging means of the heads 18 and 27 will bein alinement to maintain the bobbins with their longitudinal axesparallel to the longitudinal axis of the shuttle. It, now, it be desiredto adjust the heads '18 and 27 relatively toward or from each other, itis only necessary to unelamp the screw 33 and move the head 27longitudinally upon the hub 23 of the rotary thread guide, and duringsuch adjustment, the connection between the head 27 and the hub 22% ofthe rotary thread guide. maintains the head 27 from rotary movementrelative to the head 18, with the result that the previously establishedalincment of the bobbin end engaging means which supports the bobbinswith their axes parallel to the longitudinal axis of the shuttle,remains umlisturbed. If it is desired to remove the rotary thread guideand its connected magazine head 27, it is only necessary to manipulatethe clamping screw 25, whereupon the rotary thread guide, the hub 23 andthe head 27 may be removed as a unit.

The hub portion of the rotary thread guide may be provided with anenlarged socket 3+ for the accomniodation of the clamping washer and nut11 and 12, and likewise with a longitudinal bore for the acconnnodationof the end 35 of a thread holder 236 about which the ends of the threadsleading from the bobbins will be wound. A clamping screw 37 serves to secure the thread holder f'ili to the rotarv thread guide.
